An incredible stop, a huge save at this moment in time.

A outrageous save from Lukas Hornicek prevents Sebastian Tounekti's drilled effort bending into the bottom-right corner.

An Arne Engels cross comes into the Braga box and Víior Carvalho flicks it towards his own keeper. It's claimed.

An overhit Marcelo Saracchi cross sums up Celtic's night.

On-loan Tottenham Hotspur centre-half Alfie Dorrington comes in for Aberdeen for the injured Kristers Tobers, who he replaced in the club's Conference League squad.

Forwards Kevin Nisbet and Adil Aouchiche drop to the bench, along with midfield duo Graeme Shinnie and Emmanuel Gyamfi.

Stuart Armstrong, Topi Keskinen, Leighton Clarkson and former AC Milan forward Marko Lazetic come into the starting XI.

Just the one change from the side who secured Rangers' first win of the Scottish Premiership season at Livingston on Sunday.

Youssef Chermiti leads the line for Russell Martin's men in Graz, with Bojan Miovski dropping down to the bench. Lyall Cameron is sitting there, too.

A big boost for Sturm Graz is the return of Georgia international Otar Kiteishvili, who plays at the tip of Sturm's midfield diamond.

The playmaker grabbed 13 goals last season and has five so far this campaign, despite missing some time through injury and, more recently, personal reasons.

The Celtic midfield never really got going when they were on the field. Can the new arrivals change that?

A double Celtic change as Reo Hatate makes his comeback and Arne Engels is on.

Benjamin Nygren and Paulo Bernardo make way.

I'll be very surprised if there's only one goal scored here tonight.

Braga look dangerous every time they come forward while Celtic are trying to throw the kitchen sink at their Portuguese opponents, leaving big spaces when things break down.

There's also a certain chaotic quality to the Scottish champions tonight. Errors at the back, a goalkeeping howler and a change of formation.

I can't remember the last time Brendan Rodgers played a back three.

Joao Moutinho, at the age of 39, is on for Braga.

A player who could bring some composure to a frantic game.

Those saves are vital when you're defending the lead.

This game is really opening up now as Kieran Tierney has a back-post header saved brilliantly.

Sebastian Tounekti and Kelechi Iheanacho combine again, but the latter sees his shot blocked.

An outstanding last-ditch tackle prevents Callum McGregor getting a close-range shot away.

This is better from Celtic.

The Celtic fans bring the noise despite their clear frustration at that Kelechi Iheanacho 'goal' being disallowed.
